 paribus inaequalibus, coriaceis, glabris, integris, oblongis ad 

 oblongo-ovatis, acuminatis, basi decurrentibus, nervis utrinque 

 5 ad 8, majoribus 7 ad 13 cm longis, minoribus 3 ad 8 cm 

 longis; spicis terminalibus, 3 ad 10 cm longis, circiter 1 cm 

 diametro, densis, bracteis coriaceis, lanceolatis, 1.5 cm longis, 

 leviter f errugineo-pubescentibus ; floribus circiter 3.5 cm longis, 

 calycis lobis 5, liberis, anguste lanceolatis, 11 mm longis; corolla 

 glabra; ovario oblongo, glabro, apice f errugineo-pubescente ; 

 capsulis oblongis, 2 cm longis. 



An erect, branched, suffrutescent plant, glabrous or nearly 

 so except the inflorescences, the ultimate branches terete, brown- 

 ish, about 3 mm in diameter, the very young branchlets nearly 

 black, angled or sulcate, slightly pubescent. Leaves in unequal 

 pairs, olivaceous, oblong to oblong-ovate, entire, both surfaces 

 very densely covered with irregularly arranged cystoliths, gla- 

 brous, narrowed upward to the distinctly acuminate apex and 

 below to the decurrent base, the larger ones of each pair 7 to 13 

 cm long, 3 to 4.5 cm wide, the smaller ones 3 to 8 cm long, 2 

 to 3.3 cm wide; lateral nerves of the larger leaves about 8 on 

 each side of the midrib, of the smaller ones about 5, rather 

 prominent, the reticulations obscure. Inflorescences terminal 

 and terminating short lateral branches, spicate, 3 to 10 cm long, 

 the bracts persistent, coriaceous, lanceolate, about 1.5 cm long, 

 4 to 5 mm wide, sparingly ferruginous-pubescent, nearly black 

 when dry, narrowed upward to the bluntly acuminate apex. 

 Calyx lobes free, narrowly lanceolate, subcoriaceous, 11 mm long, 



2 mm wide, slightly pubescent. Corolla lavender, glabrous, 3.5 

 cm long, the tube narrow and cylindric in the lower 12 mm, then 

 enlarged. Stamens 4. Ovary oblong, pubescent at the apex; 

 style slender, sparingly villous. Capsules oblong, 2 cm long, 

 about 3 mm in diameter, glabrous except at the very tips which 

 are sparingly ferruginous-hirsute; seeds orbicular-ovate, about 



3 mm long, appressed-pubescent with pale-brownish hairs. 

 Luzon, Nueva Vizcaya Province, near Imugan, Bur. Sci. 1^378 



McGregor, April, 1912. The specimen closely matches Vidal 

 3012 in the Kew Herbarium bearing Clarke's unpublished manu- 

 script name which I have adopted for the species; Vidal's 

 specimen was from the Caraballo Sur Mountains and was prob- 

 ably collected on the trail between Caranglan and Dupax, hence, 

 coming from the same general region as McGregor's specimen.
